To sch/om it mag concern: Beit known that I, JOSEPH H. JOAQUIN, of thecityof- St. Louis, State. of Missouri, have J a invented certain new anduseful Improve- Inents'in Belt-Shifters, of .which the following is'afull, G1Qfi1l, a}l]d exact description, .referencebeing had to theacconi pan ying drawings, forming a part hereof. T My invention relatesto'belt-shit'ters; and

to it consists of .the novel construction, combijnation, and arrangementof parts hereinafter shown, described, and claimed.

j. .j' ,The object of this invention is toconstruct a- 'belt shilterwhich cart-be applied to any style of shifter-operatiiigmechanism andcan be adjusted tos'hift a belt at any angle.

'1 Figure 1is aperspectlve view otrny complete invention, showing itsconstruction and operative'position. ;-;':Fig. 2 is a-side-eleva-' 320131011 of'theshlfter-operating mechanism showiugitsjc'onuection withmy'invention,

Fig. .3 is 'a' detai-l top planriew of my invention. Fig; 4 Bahorizontal sectional view of a portion ofthe roller-frame, showing itsconstruc- 25.-tion and the n a'nner-inwh'ich the roller is "jrheldthereinrg a "In the-I-coust'ruction'of the device as shown providea plate 1, which may be of any de-' sirable-size and is providedin itsface with ['30. elongated slots 2, which are preferably fourinnumber'and'arranged as shown in Fig. 1.

' I the plate 1, intermediate of the slots 2, 4

I'provideapertures ii, which maybe of any I number and are for thepurpose of receiving bolts-in order to secure on the plate 1 a strip tosupport the shaft 21- at a greater distance from the roller-frame thancan be'done by p the said plate. a

The plate 1 is provided at its end 4 with an integral verticalprojection 5, consisting of two,ears 6,.each of which is provided withapertures through which are inserted bolts 7.

-' .Between the ears.6 is placed and ad j ustably held a segmentS, whichis secured inany dek sirable manner to or formed integral with thegoller-frame 9, which consists of two parts'a and I), each being bent attheir ends 10 and Iprovided with cars 11, by which said parts are heldtogether by means of bolts or screws 12, passed through apertures 13,-formed in studs 16,

. demonstration to a shifting mechanism supported fromtheslot 14,through which thebolts? pass, and

is for the purpose to adjust'the"frame Qin any angular position andretain the same in The segment 8 is'fprovided' witlia circular saidposition by the tightening of the' bol'ts 7. p w

Each of the parts'a 'a ndb' of thejframetl is provided. with apertureslo",' in"which areheld formed Rn rollersf lf7, (see Fig. 4,) saidrollers heingfor the purpose offcoming in contact with the edges of. theh elt' l8, sjoas to revolve while communicating with said belt,thus'preventing any friction upon said belt while inthe act ofshiftingand also pre venting the edges ofsaid belt from wearing,flattening, raveling, or in any way becoming is used.

shifting-operating m ee-hanism either- -horizontal, vertical, orangular, and for aclear I show myinv'ention applled ceiling, which is ofcommon construction. I attach my invention to this style of shiftingmechanism by means of U-shaped-rods 19, having their ends 20 providedwith screwthreads. These rods are passed around a bar or shaft 21, theirends 20 being passed through the elongated slots 2 and held in positionby nuts 22, passed over the threaded ends 20, coming in communicationwith the washers 23, also located. over said'en'ds and restingmutilated, as is now the case where the pres- 1 cut style of shiftersupon said plate 1. Upon the bar 21, beneath the plate 1, rests a block24, its under surface being shaped'to correspond with the shape of thebar and its top surface arranged flat to communicate with the under sideof the plate 1.

This block is to aid in tightly-sup porting my invention upon said rodwhen the U-shaped rods are tightly adj usted'thereon. By the use of theU-shaped rods and elongated slots 2 the device can be adjusted to theproper length, so as to cation with the belt. The bar 21 is held in bein'proper communisuitable hangers 25, secured to the rafters 26,

and is shift-ed by means of a lever 27, fulcrumed to said rafter andpivotally mounted to said bar at 29 in any desirable manner. By theoperation. of the lever 27 the bar 21 is shifted, carryingwith'it mycomplete invention also, the belt which passes through the 4 angle orincline in which the belt is carried.

' \Vith my improved construction the belt is in no way mutilated, as therollers 17 are allowed'to revolve, and their contact-surfaces beingconcaved it has a tendency to compress the edges ofthe belt inwardlyinstead of flattening or spreading the same. This I consider anessential feature of my invention, as by the use of the rollers the beltis saved, which is considered an item of much importance where machineryis used in manufacturv ing-shops. It also assists in the easy shiftingof the belt, asthe friction is dispensed with.

.I may also, in cases where it is necessary to apply my device where thebelt is close to the wall, release the frame from the ears-6 andplace-therein the end 10 and tightly hold the same therein by means ofthe bolts 7, passed through the apertures formed in the ears 11,

which will in this construction bring the frame 9 in direct alinementwith the plate 1.

I claim- 1. A belt shifter, having a plate, ears formed on one end ofsaid plate, a segment provided with a slot, a frame secured to saidsegment, rollers carried on said f ramc, and a means for adjusting saidframe and plate to correspond with the incline of the belt,substantially as specified.

2.' A belt-shifter, composed of a plate pro vided with slots andapertures, an extension formed onsaid plate, said extension providedwith ears, a segment provided with a slot hel d adjnsta'bly between saidears, a frame composed of two parts suitably secured together, one ofsaid parts carried by said segment, rollers carried between said parts,and rods placed through said slots for holding said plate upon a bar,substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

JOSEPH Il. JOAQUIN.
